To all whom it may concern:

Be it known that l, OTTO UHLMANN, a citizen ol' the United Statesresiding at Taunton, in the county of Bristol and State of iiiassachusetts, have invented .an Improvement' in Pneumatic Tires, of which the following description, in connection with the accompanyingdrawing, is a speciiication, like letters on the drawing representing like parts.

This invention relates to a pneumatic tire construction tor vehicles, and comprises to a certain extent the construction of the wheel ol the vehicle.

The object oi' the'invention is to provide a pneumatic tire ot the inner-tube variety, and oi such character that the inner tube may be readily and easily. removed for, repairs and renewals, and at the saine time be as little subject 'to puncture and blow-outs as iossible. l

.The nature et the invention will be apparent from the accompanying description and drawings, and will be more particularly pointed out .in the claims. l

.The drawings representa portion ol the vehicle wheel and tire sullicient to illustrate the invention.

ln the drawings, Figure l is a radial crosssection through the tire, lelly and adjacent parts. 2 is a side elevation of a sector of the vehicle wheel with its elements broken away to show the constrijlction.

The vehicle wheel :ts to its spokes and hub may be ol" any usuel construction and size which it is to The telly ot the wheel, shown at Il, `t its perii'neter, the concur-nity being et the proper size tore/ceive tlic inner lie-ll1 of the orfilii'lary inner pneumatic tube shown at B. suitable protective cushion or seat is placed between the pneumatic tube l and the eoncevitv oi the telly, and is shown an annular concavcd strip (l. /i con veiled tube cover or casing lll surrounds the upper portion oi the inner tube .lz

be used.

con caved and extends dow.A i. yard to the perimeter ol' tbe lolly, f' n which it is separated by au air space l). tube cover may be made ol any suitable inl, such as built-up rubber and canvas. ich side el the lolly is located au annular metal plate F, that extends above the lov-fer part-oi the tube cover l, so as to separate it from the outer tire casing.

nu.. made el" the usual built-up structure of canvas and"- rubber, or

lne outer tire casing,

other suitable material, is shown at Guxand is flange or heel piece ll. This outer casingY l l liorined at each lower edge with a projecting` l extends down on the exterior of the 'annular plates F and overlaps the upper edge of telly. y y

The outer casing supported interiorly by the annulariplates F is held in place at each side by a second annular plate l, provided with ohook-shaped llanges or sockets at its upper end to engage the heel piece 'H' of the 1 outer casing.

At intervals along` the perimeter of the 'wheel and preferably between each pair ot sp olres, bolts J are provided that p ass through the annular plates l and F and the telly These-bolts are preferably provided ateaeh, end with suitable metallic Washers K, bearing against the annular plates ii. The construction of the wheel and tire is thus extremely simple and strong. Whenever it is desired to remove or obtain access rangedto beven the outside of the wheel) ot the bolts J are removed and the two annular plates .l and F on the outside of the wheel can be taken olli, thus releasing the l eel piece of the outer4 casing from the annular socket el the annular plate l.

The heel piece ot' the outer casing may be split at intervals to make still easier the access to the inner tube, The opposite side of the tire may remain entirely undisturbed during theA operation et gaining access to or removingl and replacing the inneri tube from tbc outside oli the wheel.

The annular plates are so protect the inner tube against blowouts and its upper face portion vis heavily protected by the two independent coverings formed by the tube cover l@ and the outer l against puncture. lt will thus be seen that a construction is presented which resists so far as possible blow-outs and punetures and renders readily accessible the inner tube.

Having described my invention, what l claim s new and desire to secure by Letters Patent, is:

l. la vehicle wheel comprising a concaved telly, a pneumatic inner tu le resting in said telly, a convened tube eove 'fitting over the outer portion of the inner tube, a removable annular plate at each side the 'r'elly extending partially over the tubo cover, an outer casing extending; over the tube cover and upper portion ot said znnular plates and provi e arranged as to with a heel piece at each loWer edge, a removable annular plate at eaeli side the felly outside said annular plate and provided with a hook-shaped flange at its upper edge to grasp said heel piece, and means for maintaining the parts in assembled position.

2. A vehicle Wheel comprising a eoneaved felly7 a pneumatic inner tube resting` in said folly', a eonvexed tube cover iitting over the outer portion ol the inner tube, a remm'fable l an nular plate at eaeh side the ie ly extending partially over the tube cover, an outer easing.

extending over the tube cover and upper portion-of said annular plates and provided with a heel pleee at each lower edge, a ren grasp said heel piece, and a series of bolts.

passing through and uniting said annular plates and .t'elly to hold the parts in assembled position.

l'n testimony whereof, I have signed my name to this specification7 in the presence of two subscribing Witnesses,

OTTO UHLMANN.
